The common objection I've heard to geo-engineering projects is that they are incredibly difficult to reverse should the need present itself due to detrimental effects discovered part-way along. Does this objection still apply to the current popular proposals?
- rootusrootus 10y agoI recall a proposal to put sulfate particles (I think!) in the upper atmosphere, sort of like what happens with a big volcano, to try cooling things off. The downside is you have to do it constantly, the upside is that if you don't, it fades relatively quickly. So we could try it out on a pretty large scale and stop if we don't like where things are going. But that's from memory, and I could be recalling the details wrong.

- mirimir 10y agoYes, you need to get the SOX into the stratosphere, so it doesn't rain out so fast.
- Itsdijital 10y agoThis is probably what we will end up doing because it is the only one that is really viable without insane energy/time requirements. Everything else proposed would require an engineering project many many orders of magnitude greater than anything humans have done before.
